having some trouble getting windows 10 to keep
its v6 lease, it seem to fail to renew.<br>
<span
style="font-family:"Helvetica",sans-serif"><br>
From packet sniffing it seems to just be
ignoring DNSMasq's replies to the renew
packets, and then falls back to soliciting
continuously, despite being replied to.<br>
<br>
I've attached the pcap files (hopefully).
Shows that it acquires it on reboot, but fails
after the lease time is (about to?) expire -
set at 2 hours because of issues with the xbox
one getting a new address each boot (you can
see in the 2nd pcap that it renews its address
just fine).<br>
<br>
Is windows 10 borked or is it something with
my config? I'm unsure if this is a recent
development or not to be honest.<br>
<br>
Not exactly related, but I've noticed that
DNSMasq sends its v6 packets (router
advertisements and dhcpv6) from the full link
local address, even though the default address
is a manually configured fe80::1<br>
<br>
relevant config:<br>
<br>
dhcp-host=id:00:01:00:01:1a:1b:af:8c:bc:5f:f4:d8:41:bc,[::3],bc:5f:f4:d8:41:bc,10.1.2.6,xander<br>
